Can I ask what other owners' experiences have been with the battery conditioner usage particularly where you don't drive your car for say 2-3 weeks. Do most people lock their cars with the conditioners left plugged in or do you leave your car unlocked?

Has anyone experienced low battery voltage after a few weeks of non useage with the car locked and the conditioner plugged in?

I have been advised that the alarm/anti theft system does draw on the battery substantially when the car is locked.

I always use a battery conditioner on my cars, particualrly if they will not be used for more than a couple of days (I am sure that you could get away with longer periods of time).

With regards to the 458, I do not lock the doors as the connection is on the passenger's side below the dash and requires running the power cord out the door. On the Fcars with the connection in the boot, like the 612 and 599, I lock the car doors. Either way, I have not had any low battery voltage issues, even after the car sits for a month (required when I take those extended trips to Oz).

I always use the conditioner connected, door shut and car locked. Only thing I've experienced was when I have the car locked on the tender and unlock the car, remove the tender and immediately try and start the car...it doesn't. However, if I unlock the car, remove the tender and re-lock the car for a few minutes and then unlock...the car starts right up. The passenger door shuts right on top of the cord and doesn't cause any damage to the cord.

I store my F Cars over 4 months in hot humid summer Florida while being North and always use the Conditioner on the 458 and with batteries off on my 430, 512TR, and 575 with windows open to get cool AC air circulataing inside to avoid mildew. Never had a problem.

My dealer told me the battery would go dead if the car sat for seven days. I assume that is for a good battery and would only becomes less with time. I always plug the condioner in wheter in my house garage or my car storage area.

The dealer also told me if the condtioner is plugged in the car but not the electical outlet that the battery would be drawn down.

Thanks to all who responded. There are definitely some differing views. Are there any FChatters who are unable to use the car daily/weekly because of holidays/travel etc would be good to hear from you as to what you do if the car is not going to be used for 2-4 weeks.

Conditioner on
Car locked/unlocked?
Any issue on resarting after an extended break of non use?

I typically drive her once very 2-3 weeks. In between drives, she's lcoked with battery tender plugged in. No trouble starting as long as the battery charger is disconnected, the car locked then unlocked a few minutes later. I'm guessing it resets the electronics.

My dealer said that if you leave the car for 2 weeks or more, you should always use the conditioner. I close and lock my car every time I use it. Just make sure that the cord is placed as recommended (lower front of the passenger door).

Thanks Smokey, so when you leave the car without driving it for more than a couple of weeks (with conditioner on and car locked) you don't have any issue with restarting? Do you notice any change in battery charge?

Since lead-acid batteries do not like constant discharging and charging, it is good practice to keep the battery in a high charge state. Thus the use of the conditioner even for short periods of down time.

So far so good! I have not had any problem. I have yet not left it for a longer period (i.e. winter) but probably others have which could advice...

If I am driving the 458 even once every 2-3 weeks I do not use the conditioner and do not have a problem , BUT I do not lock the car as the Alarm system draws from the battery. If I don't drive the car for more than 3 weeks, then conditioner is on and the doors locked. I had no problem restarting after 3 month winter storage this year.
